Comment:
Thanks for the report. Fixed by
{{{
Thu Oct 30 09:45:28 GMT 2008 [EMAIL PROTECTED]
* Fix Trac #2674: in TH reject empty case expressions and function
definitions
}}}
Now from this program
{{{
{-# LANGUAGE TemplateHaskell #-}
import Language.Haskell.TH
$(return [FunD (mkName "foo") []])
}}}
we get the more civilised error
{{{
T2674.hs:3:2:
Function binding for `foo' has no equations
When splicing generated code into the program
}}}
Pls merge
Simon
